Taking a look at data from the Energy Information Administration, the US uses about 21.6 trillion cubic feet of natural gas per year, most of which is produced domestically (18.5 trillion cubic feet) with the difference being imported (4.2 trillion cubic feet). Proved natural gas reserves in the US amount to about 211 trillion cubic feet. If my math is correct, without taking into account any increase in demand, the US only has about 11.5 years of natural gas left. After that, we’re back to square one: importing oil from Russia, Qatar, Iran, and Saudi Arabia
Like petroleum, two-thirds of world natural gas supply exists in just a few countries. If we’re at all worried about having domestic (let alone renewable) energy sources, basing the future of US transportation on natural gas puts us right back in the same position we’re in now.
The Pickens Plan would switch us over to natural gas for the next ten years as a stopgap measure, until solar, wind, wave, geothermal, and fuel cells can be developed. A substantial increase in demand would decrease the amount of natural gas available but the increase in wind power could make up for it.
